Caribou, or reindeer, are wild, North American arctic and subarctic deer that are capable of traveling 3,000 mi (5,000 km) a year and reaching speeds of up to 50 mph (80 km/h). Each year, millions of caribou in northern Canada and Alaska migrate in large herds, using their wide, sharp-edged hooves to travel on snow and ice and even swim across wide lakes or rivers. Caribou derive their name from a word in the Mi’kmaq language meaning “snow-shoveler”—a reference to their habit of doing what? Discuss
